Odds are great that a person set the fire regardless of climate impact. Most sources I see say that climate change is the reason for the fire, and not necessarily pointing out that it's human influence that starts it. Climate change just helps spread the fire.

First we need to convince dumb motherfuckers to stop setting fires or shooting fireworks in dry seasons. Also (IMO) people who set fires that cause this much damage and loss of life should be executed by being burned at the stake
